Mastering the circular geometry of a Dresden Plate or an expansive fan border shouldn't feel like a high-stakes math project. The Creative Grids® 22-1/2 Degree Wedge Triangle Quilt Ruler is the indispensable tool for quilters who demand perfectly flat, ripple-free circular blocks. Calibrated for a precise 22.5-degree angle, this ruler allows you to construct a full 360-degree circle with exactly 16 uniform wedges. Whether you are piecing delicate, heirloom-style fans or bold, modern circular medallions, this heavy-duty acrylic template guarantees your wedges are identical and your center points align without the frustration of hand-drafted paper templates.

Why Customers Love This Tool
Customers love the CGRT225 because it turns one of the most intimidating shapes in quilting—the circular fan—into an assembly-line task. One of the biggest pain points in radial piecing is "cupping," where the quilt block ripples because the angles aren't perfectly uniform. Quilters rave about how this ruler eliminates that error entirely. By locking the acrylic into the fabric with the non-slip grip, you can slice dozens of identical wedges in minutes. It removes the stress from intricate projects like Dresden Plates, making it a favorite for both traditionalists and modern quilters alike.

Frequently Asked Questions
How many wedges make a full circle? Because this ruler is precisely set to 22.5 degrees, you need exactly 16 wedges to construct a full 360-degree circle.
Is the seam allowance included? Yes. The ruler is designed with the standard 1/4-inch seam allowance already factored into the dimensions, so your pieces will fit together correctly without any additional math.
Does the ruler slide while I am making long cuts? No. The patented Creative Grids non-slip grip is integrated along the outer perimeter. When you apply firm, even downward pressure with your hand, the grip locks the acrylic directly onto your fabric, keeping it perfectly steady while you cut the length of the wedge.
